WatchKit support

[kcharwood]

Including AFNetworking in a WatchKit 2 project results in a SystemConfiguration.h file not found error.

I am seeing this in Xcode 7 / WatchOS 2 (beta 3)

[mobileoverlord]

I've been trying to get this running in a 2.0 extension. I guess WatchOS 2 doesn't have SystemConfiguration

I'd love to hear someone has a pull request for this issue. We're looking to update our app to watchOS 2.

[ArEnSc]

Is there a work around for this guys? , other than of course not using AFNetworking lol

Anyone spotted any good examples in other libraries that have a solution for this? Still thinking about how to tackle this.

[kcharwood]

I put together a branch here with my first stab at it. Would love to hear if it working well for everyone here. Please test it and let me know.

[kcharwood]

Btw this requires TARGET_OS_IOS and TARGET_OS_WATCH which are only available in Xcode 7/iOS 9/WatchOS 2. Not sure I could merge this into master until those GM.

[kcharwood]

I guess I could add a pch line to the pod to define TARGET_OS_IOS if it isnt defined

[WKInterfaceDevice currentDevice] doesn't have model or systemVersion properties.

the umbrella header generated by cocoapods included the following files that are not part of the watch target:
#import "AFHTTPRequestOperation.h"
#import "AFHTTPRequestOperationManager.h"
#import "AFURLConnectionOperation.h"

Thanks for working on watch support!

Those methods are on WKInterfaceDevice.

Also @JARinteractive, if you bring in just the NSURLSession subspec vs the entire library through cocoapods, do things look good to you?

[JARinteractive]

@kcharwood oh, It looks like those were added in Beta 4. The NSURLSession subspec builds fine. Looks good.

[kcharwood]

@kylef any suggestions on how to best structure the podspec for watchOS support?

[jervine10]

CocoaPods version 0.38 is out with watchOS 2 support:
http://blog.cocoapods.org/CocoaPods-0.38/

The update allows you to use Pods with watchOS. As a Pod Author, you have to specify the deployment target for watchOS in the Podspec, as seen below:

Pod::Spec.new do |s|
  # …
  s.watchos.deployment_target = '2.0'
end

that's good news!

After a day of battling, I have something up and working in the watchOS_support branch. Hopefully we can get this shipped soon...

cc @cnoon @kylef

[kcharwood]

Note that iOS 6 support is removed from this podspec. Support has not yet been explicitly removed from the source itself, but that will be removed in a future update.

[cnoon]

Should this be committed? Where did this file even come from?

[kcharwood]

I'm guessing xcode generated it when I added a watch target.

[cnoon]

Newline cleanup at the top and bottom.

[cnoon]

My only other thing @kcharwood would be whether the project has actually been updated with the new deployment targets in the podspec. It would be a bummer to throw a bunch of compiler warnings for everyone that picks up the new release if there are any new deprecation warnings. Have you had a chance to see if that causes any problems?
